Given the question above, we have some `formula entities': area, force, and young modulus of steel. These entities are queried in the KG for any available linked expression. Similar to MathGraph [1]}, we utilize SymPy [2]} to convert the queried expression into a mathematical equation with variables, and to perform the calculation, we use some basic rules of precedence to fetch the results. As shown in fig. REF , we can find strain using Young's modulus and stress; however, since stress is not known, we calculate stress as the first step using force and area. This process depicts the way human thinks while answering a question with some inputs and related expressions.
